By now you have to specify --with-cxx explicite.

Maybe it is a good idea to autodetect if c++ is available during ./configure 
and turn on the r.terraflow if so?

Give it a wish or a bug report. Include that the info should also go to the
"INSTALL" file.

Mention this in the report as well.

I think what Hamish meant is that if you choose the "devel tools" (or
something like this) to be installed in most distros the gcc-c++ won't be
included. It has to be installed seperatelly usually.
